The role of Jupiter in the formation of planets.
Abstract
Five-layer models of Jupiter and Saturn and three-layer models of Uranus and Neptune are considered. Planetesimals expelled from Jupiter's zone after its formation exerted a significant effect on the formation of the planetary system. It is generally accepted at present that these planetesimals almost completely destroyed the feeding zone in the asteroid belt and reduced the amount of matter taking part in the formation of Mars by a factor of approximately 20. The model for the accumulation of terrestrial planets from two chemically very different components, A and B, is also connected with the influence of Jupiter. It is suggested that the accumulation time of Mars depends on the presence of proto-Jupiter, and is limited by the time scale for growth of Jupiter. A new scheme for the formation of Saturn, Uranus, and Neptune is proposed.
